Finding SSRF | Server Side Request Forgery
Bug Bounty Hunting - Lecture 6
Course by: Tech Hierarchy

Welcome to Lecture 6 of our Bug Bounty Hunting course, where we'll focus on one of the most critical vulnerabilities in web applications: Server-Side Request Forgery (SSRF). In this session, we'll explore the intricacies of SSRF, how it can be exploited, and techniques for identifying and mitigating this vulnerability effectively.

Server-Side Request Forgery (SSRF) is a type of vulnerability that allows an attacker to manipulate the server-side request generation process, potentially leading to unauthorized access to internal resources, data exfiltration, or remote code execution. SSRF vulnerabilities often arise from insecure input validation or inadequate access controls, making them a prime target for attackers in bug bounty programs.

During this session, we'll cover the following topics:

1. Understanding SSRF: We'll start by providing an overview of SSRF, explaining how it differs from other types of vulnerabilities and the potential impact it can have on web applications. You'll learn about the various scenarios in which SSRF vulnerabilities can be exploited, including accessing internal APIs, bypassing firewalls, and performing reconnaissance on internal networks.

2. Identifying SSRF vulnerabilities: We'll discuss common techniques and methodologies for identifying SSRF vulnerabilities during security assessments and bug bounty hunts. This includes manual testing techniques such as input validation bypass, parameter manipulation, and protocol abuse, as well as automated tools and scanners that can help detect SSRF vulnerabilities more efficiently.

3. Exploiting SSRF vulnerabilities: Once an SSRF vulnerability has been identified, we'll explore techniques for exploiting it to achieve various objectives, such as accessing sensitive information, performing port scanning, or executing arbitrary code on the server. You'll learn how to craft malicious requests and leverage SSRF to escalate your privileges and compromise the target system.

4. Mitigating SSRF vulnerabilities: Finally, we'll discuss best practices and techniques for mitigating SSRF vulnerabilities in web applications. This includes implementing proper input validation and sanitization mechanisms, restricting network access permissions, and implementing secure coding practices to prevent SSRF attacks.

By the end of this session, you'll have a comprehensive understanding of SSRF vulnerabilities, how to identify them, and techniques for mitigating the associated risks effectively. Armed with this knowledge, you'll be better equipped to uncover and address SSRF vulnerabilities in your bug bounty hunts and contribute to making the web a safer place for all users. So, let's dive into the world of SSRF and strengthen our defenses against this critical security threat!
